ErP is the abbreviation of Energy-related Products. It also refers to Energy-related Products Directive (ErP) 2009/125/EC that replaced the old Energy-using Products Directive (EuP) in November 2009. The original EuP was taken into use in 2005 to fulfill the Kioto agreement requirements for reducing carbon dioxide emissions.
The ErP broadened the range of products that were covered in EuP. Earlier only directly energy-consuming (or using) products were covered. Now ErP directive also covers the products related to energy. This could be for example water-saving taps, etc.
The idea is to cover the whole product supply chain: design stage, production, transport, packaging, storage, etc.
The former ErP directives EC 244/2009, EC 245/2009, EU 1194/2012 and Energy Label directive EU 874/2012 had been taken effect for more than10 years. Recently, the European Commission has reviewed these regulations and analyzed the technical, environmental and economic aspects of lighting products as well as real-life user behavior and issued new ErP directives EU 2019/2020 and energy label directive EU 2019/2015.
Subject Matter And Scope of New ErP Regulation
1. This Regulation establishes ecodesign requirements for the placing on the market of
(a) light sources;
(b) separate control gears.
The requirements also apply to light sources and separate control gears placed on the market in a containing product.
2. This Regulation shall not apply to light sources and separate control gears specified in points 1 and 2 of Annex III.
3. Light sources and separate control gears specified in point 3 of Annex III shall comply only with the requirements of point 3(e) of Annex II.
Energy Efficiency Classes And Calculation Method
The energy efficiency class of light sources shall be determined as set out in Table 1, on the basis of the total mains efficacy ηTM, which is calculated by dividing the declared useful luminous flux Φuse (expressed in lm) by the declared on-mode power consumption Pon (expressed in W) and multiplying by the applicable factor FTM of Table 2, as follows:
ηTM = (Φuse/Pon) × FTM (lm/W).
Table 1
Energy efficiency classes of light sources
| Energy efficiency class | Total mains efficacy ηΤM (lm/W) |
| A | 210 ≤ ηΤM |
| B | 185 ≤ ηΤM < 210 |
| C | 160 ≤ ηΤM < 185 |
| D | 135 ≤ ηΤM < 160 |
| E | 110 ≤ ηΤM < 135 |
| F | 85 ≤ ηΤM < 110 |
| G | ηΤM < 85 |
Factors FTM by light source type
Table 2
| Light Source type | Factor FTM |
| Non-directional (NDLS) operating on mains (MLS) | 1,000 |
| Non-directional (NDLS) not operating on mains (NMLS) | 0,926 |
| Directional (DLS) operating on mains (MLS) | 1,176 |
| Directional (DLS) not operating on mains (NMLS) | 1,089 |
EPREL: What Lighting Businesses Need To Know
Working with new energy labelling is now unavoidable for the lighting industry, so it’s worth familiarising yourself with its standard requirements for its use.
New energy labels cannot be publicised prior to 1st of September 2021
ALL applicable products, either on the market or intended to be placed onto the market, must be registered in the EPREL database if intended for the EU marketplace
ALL applicable products, either on the market or intended to be placed onto the market, must have the new energy rating label, suitable for the EU market and/or UK market
Energy Related Products (ERP) must be compliant to their respective efficiency regulations – for lighting – if it’s in scope – that’s the SLR.
As of 1st September, 2021, ONLY SLR compliant products can be placed on the market, or if already placed on the market they may continue to be saleable.
Data within the EPREL database must be fully complete in order for the item to be published as live – and therefore considered saleable.
Products on the market with incomplete EPREL registrations will be deemed non-compliant by market surveillance.
